Watch horror movies without the fear of having to cover your eyes when things get scary with these ingenious Theater Safety Glasses created by Aisen Caro Chacin in collaboration with Shawn Lauriat. Inspired by the Joo Janta 200 Super-Chromatic Peril Sensitive Sunglasses from Douglas Adams’ The Hitchhiker’s Guide to the Galaxy series, which keep the wearer relaxed by turning black at the first hint of danger, the Theater Safety Glasses lower a curtain to cover the wearer’s eyes whenever their pulse quickens and triggers a sensor.

I made a pair of glasses that cover your eyes when you are scared or nervous. These would be specially useful at the movie theater, where some graphic scenes are excruciating enough for covering your eyes. The glasses would have the pulse sensor on an earring clipped to one of the lobes. When the sensor detects an exaltation in pulse servos on both sides of the glasses will close the curtains covering both eyes. The arduino board and two demo buttons are housed in a small plastic box that fits in your pocket.

If you’d like to see more of Aisen Caro Chacin’s work in the flesh, her Sensory Pathways series, which explores sensory experiences through cross-modal computer interaction, is currently on display at the Museum of Arts and Design’s NYC Makers exhibition.
